We don't have access to a g77 under Linux that works, so our INSTALL
document recommends the use of /usr/bin/fort77 as the Fortran compiler
instead.  INSTALL includes a couple of configure settings that worked
for us.

Phil Austin <address@hidden> reported that the following worked on his
Debian 1.3 Linux system with g77:

    $ uname -a
    Linux curlew 2.0.27 #2 Tue May 6 17:57:24 PDT 1997 i686

    CPPFLAGS='-Df2cFortran -DNDEBUG'
    CC=/usr/bin/cc # version 2.7.2.1-4
    CFLAGS=-O
    FC=g77 # version 0.5.19.1-1
    FFLAGS=-O
    CXX=/usr/bin/c++

Jan Polcher reported that he added "-ff2c" to his FFLAGS option and it
worked.

So all I can recommend is that you try one of these alternatives.
Please let us know the details if you find a combination that works.
